Introduction of WNS gas / oil fired steam boiler:

WNS series horizontal internal combustion boiler is a boiler shell type 3 passes wetback oil/gas fired boiler. After fuel is being atomized by burner, flame is full of the wave furnace and transfer heat via furnace wall, this is 1st pass; the high temperature smoke is collected in reversal chamber and then enters 2nd pass which is grooved tubes bundle area; after heat convection, air temperature gradually falls and goes to front smoke box and turn to 3rd pass, which is smooth tubes bundle area, and then enters chimney passing back smoke box and exhausted to the atmosphere.

Technical advantages:

1. Digitized manufacture
The key part such as material cutting, rolling, drilling are proceeded by advanced CNC machining process to reduce the assemble stress and extend boiler working lifetime.
The front and back smoke chamber plates are cut by CNC plasma cutting machine and looks tidy and beautiful.

2.Easy operation and maintenance
Fully automatically operating, with automatically adjustment and protection of burning, water level, temperature and steam pressure.

3. Longer working life
Smoke tube and tube sheet connection is expanded first to eliminate the gap between them, then adopt automatic argon arc welding to relief the stress and expand boilers working life.
Longitudinal and girth joint adopt advanced automatic submerged-arc welding for good welding quality. All longitudinal and girth joint will have 100% radiographic inspection.
Fin tube us ND steel or stainless-steel material which avoid low temperature corrosion.
Inspection procedure point is set up to guarantee the sequence of expanding and welding, avoid cracking of the tube sheet holes.

4. Less fuel consumption
High quality aluminum silicate fiber is used with fire clay insulation, to control the boiler body temperature below 45℃ to control heat lost.
Sufficient steam storage room and heating area makes boiler to generate high quality steam and high thermal power.
Condenser is added to reuse the waste heat of the exhausted smoke to increase feeding water’s temperature and reduce emission temperature, which can increase the thermal efficiency above 98% and save operating cost.

TGN-PE-03 Cracking in Fire Tube Boilers - ATH

Cracking in fire-tube boilers at welded joints is a frequent, costly and potentially dangerous occurrence. The shortest recorded time for serious cracking to leak is 3 years, representing less than 20,000 cycles, and occurred on a laundry boiler subjected to frequent and rapid firing.

Firetube Boiler Tubesheet Repair | HEAT TRANSFER SOLUTIO

Jim Manley, with over 40 years of boiler repair experience on water tube, fire tube, cogeneration and locomotive boilers, and Jeff Welton a degreed Mechanical Engineer and combustion expert, drove to the job site in the Santa Barbara area to inspect and make necessary emergency repair recommendations.

Excessive Cyclic Operations in Firetube Boile

the tube leaks of firetube boilers in the 1950s. This report recommended the use of a fillet weld on the hot pass of the flues/fire tubes to reduce hoop stress caused by cyclic operations and to provide a heat sink to remove heat stress from the end of the tube extending out from the tube sheet.

Water Tube Boiler Parts and Functions - Boilersin

We briefly discuss about Water tube boiler parts and functions. D type water tube boiler. In the water tube boiler, the water and steam flow inside the tubes and the hot gases flow over the outside surfaces. Where as in fire tube boilers hot gases from combustion travels through the tubes. flue gases produced from furnace where fuel is burnt

Difference Between Fire Tube Boiler and Water Tube Boil

Fire-tube boiler: Fire-tube boiler is those boiler in which the fire or hot gas is present inside the tubes and water surrounds these fire tubes. Since fire is inside the tubes and hence it is named as fire tube boiler. The heat from the hot gases is conducted through the walls of the tube to the water.

Types of Boilers - Forbes Marsha

The different types of boilers find their use in different applications. As the time has passed, more efficient types of boilers have replaced the old and inefficient ones. This article elaborates on different types of boilers and the boiler classification. Boilers can be broadly classified as shell tube and water tube boilers.

Fire-tube boiler - Wikiped

A fire-tube boiler is a type of boiler in which hot gases pass from a fire through one or (many) more tubes running through a sealed container of water. The heat of the gases is transferred through the walls of the tubes by thermal conduction, heating the water and ultimately creating steam.. The fire-tube boiler developed as the third of the four major historical types of boilers: low
